World Naked Bike Ride (WNBR) is a highly organised, if a little dormant wiki, operational since 2006, on the very interesting activity of organised cycle rides whilst naked!

Print and broadcast media are actively canvassed to cover the events to publicise their aims. It's dress code is "Bare As You Dare"... there is no compulsion to cycle completely naked if you are personally uncomfortable, and some cyclists will partake with just their intimate parts covered.
